First of all, don't worry - this book isn't as dodgy as we feared it would be. Yes, Olivia Davidson, who seems to have had a personality transplant, is madly in love with hunky art teacher Stuart Bachman, but Stuart has no interest in her. Olivia, however, convinces herself that he does - after all, who could resist her funky new giant earrings? This is a scenario that could actually do with Elizabeth meddling with other people's personal lives but for once she decides to stay out of it. Meanwhile Jessica is determined to use her extremely poorly organised electronics class to humiliate Lila, Mr Collins gets the warm welcome he deserves and we end up with a genuinely exciting cliffhanger. No wonder this episode is ridiculously long!
